Deltamethrin is a widely used insecticide belonging to the class of pyrethroid. Although the neurotoxicity of pyrethroids including deltamethrin is well established, it is still unclear whether exposure to deltamethrin during neonatal period has any deleterious effect on the survival of the Purkinje cells in the cerebellum. In the study, we investigated the total number of Purkinje cells in exp...

Treating male albino rats with the pyrethroid insecticide, deltamethrin induced various histological changes in the liver. These changes included congestion of blood vessels, leucocytic infiltration, cytoplasmic vacuolization of the hepatocytes and fatty infiltration. Deltamethrin also caused significant elevation in serum ALT and AST enzymes after 2 and 3 weeks of treatment. . Silymarin, an ex...

We have compared the sublethal effects of two insecticides in the honeybee (imidacloprid and deltamethrin) in both semi-field and laboratory conditions. A sugar solution containing 24 microg kg(-1) of imidacloprid or 500 microg kg(-1) of deltamethrin was offered to a colony set in an outdoor flight cage. In contrast to imidacloprid, deltamethrin had lethal effect on workers bees. The contaminat...

Effect of the deltamethrin, which is extensively used synthetic pyrethroid, was investigated on the lipase activity of Poecilia reticulata in the present study. One control and five experimental groups were exposed to different concentrations of deltamethrin. Three experiments, including 60 guppies each, were conducted. Titration method was used in order to determine the lipase activity. Lipase...

Pyrethroids are commonly used insecticides that are considered to pose little risk to human health. However, there is an increasing concern that children are more susceptible to the adverse effects of pesticides. We used the zebrafish model to test the hypothesis that developmental exposure to low doses of the pyrethroid deltamethrin results in persistent alterations in dopaminergic gene expres...

Deltamethrin is a broad-spectrum insecticide mainly used to protect crops, fruit and vegetables from mites, ants, weevils, beetle etc. Thus deltamethrin contaminated food of commercial poultry diet may cause toxic effects in broilers and indirect adverse effects on human through food chain. Therefore, hematological and biochemical alterations in White Leghorn birds due to deltamethrin induced t...

The immune system is the most vulnerable system regarding toxicity of pesticides. Any alteration in the immune functions makes an individual immunocompromised and more susceptible to cancer, infections, autoimmunity and allergies. Deltamethrin is the most popular type 2 pyrethroid insecticide which is widely use in agriculture and home due to restriction on the organophosphate insecticides. Due...

Type-II pyrethroids, including deltamethrin, are highly toxic to Paramecium tetraurelia, an organism that does not possess a voltage-sensitive sodium channel. Previous research has established that deltamethrin is toxic to P. tetraurelia in mortality bioassays at concentrations as low as 10210 and 10211 M under resting and depolarizing conditions, respectively. Deltamethrin, likewise, stimulate...

susceptibility levels of a lab strain of an. stephensi to who standard papers of ddt 4%, dieldrin 0.4%, malathion 5%, permethrin 0.25%, lambdacyhalothrin 0.1%, cyfluthrin 0.1% and deltamethrin 0.025% were determined in our laboratory in 1999. results showed that at the diagnostic dose of insecticides this species exhibited resistance to ddt and dieldrin with mortality rate of 54±2.5% and 30±2.5...

Deltamethrin is -cyano pyrethroid insecticide used extensively in pest control. Although initially thought to be least toxic, a number of recent reports showed its toxicity in mammalian and non-mammalian laboratory and wildlife animal species. Lycopene is the pigment that gives tomatoes their red color and is one of four main carotenoids normally found in human blood and tissue. The present stu...
